Although such systems (still being researched) use reflectors rather than lenses. And oil rather than water - oil can absorb much more heat from the concentrated sunlight without boiling, which would break down the process. The steam is generally produced in a separate heat exchanger, just as with other types of steam turbines. Actually, you can.
